本文的目的在于建立一种提高诊断转移性肝脏疾病灵敏性的方法。这一方法的原理是:正常肝脏由肝动脉供给约25～30%血液。其余的通过门静脉供应;肝脏存在原发或转移性肿瘤时,正常的血流供应发生紊乱,以至由肝动脉供给大部分血流量。本文通过228例 The purpose of this article is to establish a method for improving the sensitivity of diagnosing metastatic liver disease. The principle of this method is that a normal liver supplies about 25 to 30% of blood from the hepatic artery. The rest is supplied through the portal vein; in the presence of primary or metastatic tumors in the liver, the normal blood supply is disrupted and the hepatic artery supplies most of the blood flow.
